Woovly is India's leading social commerce platform for fashion, beauty, and lifestyle products targeting Tier II and Tier III cities. Founded by Neha Suyal in 2019 (pivoted from adventure experiences to social commerce in 2020), the company grew to over a million users and achieved 30% monthly growth primarily through word of mouth and a community of 10,000 micro/nano influencers from 1000 college partnerships. 72% of users come from organic/word-of-mouth channels, with 61% of revenue generated by micro and nano influencers.
Blocker X (formerly Fund Switch Technology) is a YC-backed digital wellness app helping people overcome pornography and social media addictions. The company started as a Chrome extension with 600k+ users and pivoted to mobile-first with a 1M+ install base on Android, combining blocking technology, community support, and gamification.
David's Tea was founded in 2007 by David Segal and his distant cousin to make tea fun and accessible to mainstream North American consumers. The company grew to a $200 million revenue business with a $1 billion market cap at its peak before going public on the Nasdaq. Segal sold his stake in 2016 after internal management conflicts made the company lose focus on its core business.
Italic is a membership-based e-commerce marketplace founded by 25-year-old Jeremy that sources high-quality products from the same factories that produce for luxury brands like Gucci and Prada, then sells them at 60-80% lower prices. Launched about two years ago, the company recently crossed 10,000 members with strong unit economics: members spend approximately $600-700 in their first six months, averaging one order per month.
Tai Lopez is an entrepreneur and investor who built multiple income streams through digital marketing and course sales before pivoting to acquiring distressed retail brands. Through his company Retail E-Commerce Ventures (with partner Dr. Alex Mayor), he acquires well-known but struggling brick-and-mortar brands like Pier One and Dress Barn, converting them to e-commerce models. His early success came from Google AdWords lead generation for life insurance and financial services, achieving six figures within a year of starting in 2001.
Gold Belly is a marketplace that connects customers with famous regional specialty foods and products from local restaurants and shops across the US, shipping them nationwide with special preservation packaging. Founded by Joe Ariel (former CEO of Deliver.com, Y Combinator alumnus), the company raised $33 million and is experiencing explosive growth, with many partner restaurants showing delayed delivery due to high demand.
Pioneer is a founder-scouting platform that identifies promising people working on interesting ideas around the world using psychometrics and machine learning, then creates and funds companies for them on the spot. Founded by Daniel (age 28), a former Apple executive and Y Combinator partner with angel investments in companies like Uber, Coinbase, and Figma, Pioneer operates as a venture capital generator rather than a traditional accelerator, having invested in approximately 90 people in its first year with check sizes in the tens of thousands of dollars. The company is partially funded by Daniel and investors including Stripe co-founders and Marc Andreessen.
Big Ass Fans started in 1999 with founder Kerry Smith manufacturing and selling large-diameter ceiling fans (6-24 feet) for industrial spaces. Despite expecting to sell 1,000 fans in the first year, they sold only 142—but received positive customer feedback that gave Kerry faith to continue. Over 19 years of bootstrapped growth, relentless R&D investment, and a focus on direct customer relationships, the company built an 80% market share and sold for $500 million in 2017, with Kerry distributing $50 million in proceeds to 150+ employees.
Sean built an ascending-clock second-price auction platform to resolve disputes over valuable new top-level domains (.app, .blog, .church, etc.) worth hundreds of millions. After 8 months of grueling direct outreach to reluctant tech giants, he convinced Google and other major companies to use the platform, which has since facilitated auctions exceeding $100 million per domain. The business model charges 4% commission on auction proceeds.
Keith Wasserman and his cousin Damian started Gelt in December 2008 by purchasing a single fourplex in Bakersfield for $150,000 with just 2.5% down ($5,000 borrowed, $10,000 credit card cash advance) during the financial crisis. Over the next decade, they grew to manage over $1 billion in real estate assets by focusing on value-add multifamily properties through strategic renovations and raising capital from 700+ accredited investors. Galena Wasserman runs Sky, a parallel real estate development company that acquires and renovates buildings through ground-up construction and adaptive reuse, with both operating on the principle of 'making money on the buy' by identifying undervalued properties and creating value before exit or hold.
Ramon Van Meer built a soap opera news blog from scratch without coding skills, writing experience, or any passion for soap operas themselves. By identifying high engagement on Facebook fan pages, hiring freelance writers, and reverse-engineering successful content strategies, he grew the site to $400-500k monthly revenue in 2-3 years and sold it for $8.75 million cash. The business demonstrates that founder-market fit isn't required if you can identify passionate audiences, find the right distribution channels, and execute systematically.
On Deck Course Creators Fellowship is a cohort-based online education program led by Andrew Barry that teaches course creators how to build and scale educational products. The platform emphasizes community learning, practical frameworks (the "three Ps": personal meaning, peer-to-peer learning, and prompts to action), and has grown through word-of-mouth and social proof from successful course creators like Marie Poulin and Ali Abdaal.
Crabi is Mexico's first full-stack auto insurance startup, founded in 2017 by Javier Orozco, Arnoldo de la Torre, and Cristina Carvallo.

The platform offers free listings with premium features like national SEO and video ads, requiring a 3.5+ online reputation score for inclusion.
